Katie Peridot quite likes being ordinary, but unfortunately for her some strange things have been happening in the town of Witchfield, and, even worse, they seem to be connected to her. On top of that her best friend, Mayuri, doesn’t seem to be her best friend anymore, a sinister sponsorship programme is taking over her school, her mother is more crazy than usual and the only person who really seems to understand her is a mysterious cleaning lady from school. Then she teams up with Themba, the cleverest (and most unpopular) boy in school and together, their investigation takes them deep into the town’s old mine. What they find there is more terrible than they could have imagined. Can they save Witchfield before it’s too late?
